Payment may also be made by delivery of shares of the Company's Common Stock or Preferred Stock having an aggregate fair market value (as determined in good faith by the Board of Directors) equal to the Purchase Price on the date of exercise. On any partial exercise the Company at its expense will forthwith issue and deliver to or upon the order of the Holder a new Warrant or Warrants of like tenor, in the name of the Holder or as the Holder (upon payment by the Holder of any applicable transfer taxes) may request, providing in the aggregate on the face or faces thereof for the number of shares of Common Stock for which such Warrant or Warrants may still be exercised. -2- 2.

ADJUSTMENT FOR DIVIDENDS IN OTHER STOCK OR PROPERTY; RECLASSIFICATION. In case at any time or from time to time the holders of Common Stock (or Other Securities) shall have received, or (on or after the record date fixed for the determination of shareholders eligible to receive) shall have become entitled to receive, without payment therefor, (a) other or additional stock or other securities or property (other than cash) by way of dividend, or (b) any cash (excluding cash dividends payable solely out of earnings or earned surplus of the Company), or (c) other or additional stock or other securities or property (including cash) by way of spin-off, split-up, reclassification, recapitalization, combination of shares or similar corporate rearrangement, other than additional shares of Common Stock (or Other Securities) issued as a stock dividend or in a stock-split (adjustments in respect of which are provided for in Section 5), then and in each such case the Holder, on the exercise hereof as provided in Section 1, shall be entitled to receive the amount of stock and other securities and property (including cash in the cases referred to in subsections (b) and (c) of this Section 3) which the Holder would hold on the date of such exercise if on the Issue Date the Holder had been the holder of record of the number of shares of Common Stock called for on the face of this Warrant and had thereafter, during the period from the Issue Date to and including the date of such exercise, retained such shares and all such other or additional stock and other securities and property (including cash in the cases referred to in subsections (b) and (c) of this Section 3) receivable by him as aforesaid during such period, giving effect to all adjustments called for during such period by Section 4. -3- 4. ADJUSTMENT FOR REORGANIZATION, CONSOLIDATION, MERGER. (a) In case at any time or from time to time, the Company shall (i) effect a reorganization or (ii) consolidate with or merge into any other person, then, in each such case, the Holder, on the exercise hereof as provided in Section 1 at any time after the consummation of such reorganization, consolidation or merger, as the case may be, shall receive, in lieu of the Common Stock (or Other Securities) issuable on such exercise prior to such consummation or such effective date, the stock and other securities and property (including cash) to which the Holder would have been entitled upon such consummation as the case may be, if the Holder had so exercised this warrant, immediately prior thereto, all subject to further adjustment thereafter as provided in Sections 3 and 5. (b) Upon any reorganization, consolidation or merger referred to in this Section 4 (except as set forth in the second parenthetical in Section 6(c)), this Warrant shall continue in full force and effect and the terms hereof shall be applicable to the shares of stock and other securities and property receivable on the exercise of this Warrant after the consummation of such reorganization, consolidation or merger, as the case may be, and shall be binding upon the issuer of any such stock or other securities. 5. ADJUSTMENT FOR EXTRAORDINARY EVENTS. In the event that the Company shall (a) issue additional shares of the Common stock as a dividend or other distribution on outstanding Common stock, (b) subdivide or reclassify its outstanding shares of Common Stock, or (c) combine its outstanding shares of Common stock into a smaller number of shares of Common Stock, then, in each such event, the Purchase Price shall, simultaneously with the happening of such event, be adjusted by multiplying the then Purchase Price by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately prior to such event and the denominator of which shall be the number of shares of Common Stock outstanding immediately after such event, and the product so obtained shall thereafter be the Purchase Price then in effect. The Purchase Price, as so adjusted, shall be readjusted in the same manner upon the happening of any successive event or events described herein in this Section 5. The Holder shall thereafter, on the exercise hereof as provided in Section 1, be entitled to receive that number of shares of Common Stock determined by multiplying the number of shares of Common Stock which would be issuable on such exercise as of immediately prior to such issuance by a fraction of which (i) the numerator is the Purchase Price in effect immediately prior to such issuance and (ii) the denominator is the Purchase Price in effect on the date of such exercise. 6. NO IMPAIRMENT. The Company will not, by amendment of its Certificate of Incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, or any other similar voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such action as may be necessary or appropriate in order to protect the rights of the Holder -4- against impairment due to such event. Without limiting the generality of the foregoing, the Company (a) will not increase the par value of any shares of stock receivable on the exercise of the Warrant above the amount payable therefor on such exercise, (b) will take all action that may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable shares of stock, free from all taxes, liens and charges with respect to the issue thereof, on the exercise of all of the Warrants from time to time outstanding, and (c) will not consolidate with or merge into any other person or permit any such person to consolidate with or merge into the Company (if the Company is not the surviving person), unless such other person shall, pursuant to Section 5 hereof, expressly assume in writing and will be bound by all the terms of this Warrant (except where the consideration with respect to such merger is cash or publicly-listed securities). 7. CHIEF FINANCIAL OFFICERS' CERTIFICATE AS TO ADJUSTMENTS. In each case of any adjustment or readjustment in the shares of Common Stock (or Other Securities) issuable on the exercise of the Warrants, the Chief Financial Officer of the Company will promptly compute such adjustment or readjustment in accordance with the terms of this Warrant and prepare a certificate setting forth such adjustment or readjustment, the Purchase Price resulting therefrom and the increase or decrease, if any, or the number of shares purchasable at such price upon exercise of the Warrant, and showing in detail the facts and computation upon which such adjustment or readjustment is based.
